 the heart graph is not a function
=======================
 -45,-55,-65
=======================
A(30) =  -1 + (30 - 1) * 2 = -1 + 29 * 2 = -1 + 58 = 57 <==
======================
 the vertical line test
======================
range is { 1,7,13 }
======================
I am having a problem with the last one....with the points that are listed, it is not a function...because u have 2 x- values that are 4

Answer:

Ans1:  Heart shaped graph

Ans2:  option:C

Ans3:   option:D

Ans4:    option:A

Ans5:     option:D

Step-by-step explanation:

Ans1:  Heart shaped graph is not a function.

" since for a graph to be a function: any line passing through the domain and parallel to the co-domain should intersect the graph exactly once ".

also we can see from some examples in a figure attached to the answer.

Ans2:  we are given a sequence as:   -5,-15,-25,-35

as the given sequence is an Arithmetic Progression(A.P.) with a common difference [tex]d=-10[/tex]

Hence the next three terms of the sequence are:   -45,-55,-65

Ans3: we are asked to find the 30th term of a sequence

[tex]a_{n}=-1+(n-1)\times 2[/tex]

[tex]a_{30}=-1+(30-1)\times 2\\ \\a_{30}=-1+29\times2\\ \\a_{30}=-1+58\\ \\a_{30}=57[/tex]

Hence, the 30th term of the given sequence is 57.

Ans4: The vertical line test is used to determine if the graph is a function.

Ans5:   we are given a function f(x)=3x-5

with domain={2,4,6}

range of f(x):

when x=2  f(x)=3×2-5=6-5=1

when x=4   f(x)=3×4-5=12-5=7

when x=6   f(x)=3×6-5=18-5=13

Hence, range of f(x)={1,7,13}.

Ans6:   the given set of ordered pair is: {(4,-2),(-1,-1),(0,0),(1,-1),(4,2)}

As from the given set we could see that '4' has two images.

As '4' is mapped to '-2' and '2'{ since, the given ordered pair is (4,-2) and(4,2)}

Hence, f can't be a function.
